Abstract

A hot runner nozzle structure provides insulation to reduce heat transfer to a utilizing tool and to increase accuracy of temperature measurement and control. A shaft foot (48) of extremely low heat conductivity is used to separate a point of contact between a feed tube shaft (17) and the tool (27). The shaft foot (48) may be formed of titanium for example. An insulating cap (53) of extremely low heat conductivity surrounds the shaft foot (48) in the vicinity of the nozzle tip (26). The cap (53) may be formed of PEEK or of titanium for example. Gaps may be provided between the insulating cap (53) and shaft foot (48) and/or between the shaft foot (48) and feed tube shaft (17). In an alternate embodiment having smaller dimensions, an insulating ring (54) is provided at the end of the feed tube shaft. The structure, combined with a positioning sleeve surrounding the feed tube shaft, permits placing a heat sensor (34) extremely close to the nozzle tip (26) in order to obtain more accurate temperature control. <IMAGE>
